For example, here’s how to authenticate a bearer token: – – Since Permit isn’t tightly coupled to a framework or data model, it gives you complete control over how you write your authentication logic—the exact same way you’d write any other request handler.

But if you’ve run into any of these problems before while adding authentication to a Node.js API, you might like Permit.

Permit was designed with authenticating APIs in mind, so it’s able to be much leaner than others, since it doesn’t need to handle complex OAuth integrations with Facebook, Google, etc.

Due to its simple interface, Permit makes it much easier to write and reason about your actual authentication logic, because it’s exactly like writing any other route handler for your API.

Permit’s API is very flexible, allowing it to be used for a variety of use cases depending on your server framework, your feelings about ORMs, your use of promises, etc.

GitHub is where people build software. More than 27 million people use GitHub to discover, fork, and contribute to over 80 million projects.

GitHub is home to over 20 million developers working together to host and review code, manage projects, and build software together.

An unopinionated authentication library

for building Node.js APIs.

Usage • Why? • Principles • Examples • Documentation

Permit makes it easy to add an authentication layer to any Node.js API. It can be used with any of the popular server frameworks (eg. Express, Koa, Hapi, Fastify) and it can be used for any type of API (eg. REST, GraphQL, etc.) due to its simple, unopinionated design.

Permit lets you authenticate via the two schemes most APIs need: a single secret bearer token, or a set of username and password credentials. For example, here’s how to authenticate a bearer token:

New types of schematics will be available, that will be able to ease the integration of new libraries, add capabilities, and update your npm dependencies automatically (framework libraries), update your code and libraries too (RxJS + Material) inside your current Angular project.

NgConf is THE Angular conference that rule them all and happened some days ago. A lot of new things for Angular have been announced. This article sums up all the goodness from the Angular team, be sure to check resources link if you want to see additional content like the slides and the video!

Announcing Angular LTSNg-conf @Brad Green Keynote 2018 — PublicFirst, the Angular Team will support in long term each of the releases. That means that each major version of Angular will be supported for 12 months at least. During these months, the team will release patches and fixes to the current version. That will give you the time to catch up, and upgrade you application at your own pace.

Aligning library releasesNg-conf @Brad Green Keynote 2018 — PublicThe multiple Angular packages and the main Angular projects maintained by the Angular Team will have aligned library releases. This will mentally ease the link with all the multiple dependencies you have in your project.

New CLI featuresA lot of feature of Angular 6 will help you improve the experience using the Angular CLI, making it easier and faster.

Extending the CLI with SchematicsThe first one concerns extending the CLI with Schematics. Schematics exists to automate some redundant tasks that you need to do when you’r developing with Angular. Schematics are currently used as a way to create, easily and fast, some type of files, like components, directives, pipes, services… but this is more than that. If you want…

Node.js was developed by Ryan Dahl in 2009, and the platform has now become an exceptional choice for real-time web application development that boosts ROI by providing a highly interactive user experience.

Since Node.js uses an event-driven, non-blocking I/O model, it’s very efficient and lightweight for in-memory usage and data dense real-time web applications that work on multiple devices.

With Node.js, developers can automatically send and synchronize data between server and the client side as it allows developers to write JavaScript for both the server and client.

Meteor, a web app framework created on top of Node.js, offers support to the same codebase for the client and the server.

All the virtues of Node.js mentioned above are the major reasons why many companies now consider Node.js as a good technology for running heavy load web applications and allowing teams to move much faster in bringing their designs to life.

It often happens that a game-changing technology enters the tech market with a boom, but passes into extinction later. However, that’s certainly not the case with Node.js, which is an open source, cross-platform built on Chrome’s JavaScript runtime.

Node.js uses the V8 engine developed by Google which allows compilation of JavaScript into native machine code and fast execution. Since Node.js uses an event-driven, non-blocking I/O model, it’s very efficient and lightweight for in-memory usage and data dense real-time web applications that work on multiple devices.

With Node.js, you can execute common web application tasks very fast, like reading or writing to the database, reading and writing to network connections and reading or writing to the file system. Node.js is a blessing for developers who want to build quick, robust web applications that can effectively deal with parallel…

We can do: – Rather than: – However if you’re still interested in the whole Response object you can observe for it: – // { observe: ‘response’ });Query parametersOne thing that might not be as intuitive is the way that it handles query parameters.

The HttpClient API was introduced in the version 4.3.0. It is an evolution of the existing HTTP API and has it’s own package @angular/common/http.

One of the most notable changes is that now the response object is a JSON by default, so there’s no need to parse it anymore. We can do:

Rather than:

However if you’re still interested in the whole Response object you can observe for it:

// { observe: ‘response’ });Query parametersOne thing that might not be as intuitive is the way that it handles query parameters. You can’t just really pass a Plain Old JavaScript Object (POJO) over and expect it to be assigned as a query parameter of the request like you would with any other option that can be passed to the options object of the GET call.

import { HttpParams } from ‘@angular/common/http’;const params = new HttpParams().set(‘q’, { params });This is a bit verbose. Luckily there’s already a pull request in place to enable the usage of object maps for parameters and headers of GET requests.

Type checking responsesThanks to TypeScript Generics you type HTTP method youâ€re calling and the response will get be of that same type:

interface LoginResponse {

accessToken: string;

accessExpiration: {

login: ‘foo’,

password: ‘bar’

}).subscribe(data = {

console.log(data.accessToken, non-JSONÂ dataAlthough itâ€s the most common, sometimes youâ€ll deal with different sorts of data. This…

Step 1: An Angular Starter ProjectI prefer Angular Webpack Starter since it comes out of the box integrated with NgRx, Hmr and Webpack. You are free to choose which ever starter you want but this article won’t talk about setting up NgRx for those.

Step 2: Setup Keycloak JSIt is recommended to load the keycloak JS file from the keycloak server and this is the approach I would be using for this article as well.

Open Index.html and add the keycloak(.js|.min.js) file from your keycloak server location.

You can use webpack to inject the keycloak url. Since we have a dev and production, the keycloak url is dynamically injected depending on the environment.

Create a folder named keycloak inside src/app which will include the following discuss each file and what they do.

The keycloak-api.service.ts is an Observable wrapper for the keycloak.js providing three key functionality

1. Is the user already logged in

2. Perform on-demand login when required

3. Update the token before making the api call

The keycloak.actions.ts as you all have guessed it, is the redux actions.

The keycloak.effect.ts intercepts the actions fired by the login button and calls the keycloak-api.service.ts where the side effect takes place and then returns an action if the login/checklogin was successful.

The keycloak.reducer.ts is the simplest implementation like any other reducer just store and update the state based on the action fired.

For example: – export class AdminService { – data = providers: [AdminService, AdminDataService] – })I see a lot of people whose first instinct is to just put all their services in @NgModule() declarations without thinking about the consequences.

The sole purpose of the service is to share data between child’s components and to provide a couple of helper’s methods.

So, we just stick it in the component providers and make it a non-singleton service.

@Component({ – selector: ‘admin-tab’, – providers: [AdminService, AdminDataService] – })The benefit is that when Angular destroyed the component, Angular will also destroy the service and release the memory that is occupied by him.

Why Vue 2 beats Angular 2 and ReactWe started a contest at my job to see which framework was the best. At first it was going to be Angular 2 vs React, but then a friend mentioned that people who used Vue wished they had known about it sooner and preferred it over React.

I built a small dynamic single page in a single app in Vue 2, Angular, and React and I measured things like learning time, difficulty, and boilerplate. The single page demonstrated the basic features you would use in a production quality app.

I tested Vue and at first was displeased at how there wasn’t as much community support around it. So I moved onto React. I’ll come back to that.

ReactReact was easy to learn. It took about 2 days to find my way around. The boiler plate was significantly less than Angular 1 and despite my initial disgust, was actually fun to write in. It’s Redux state management revolutionized my world and would make building future apps much more organized.

Angular 2Angular 2 is a powerful framework but not my cup of tea and I prefer not to use it. It adds a lot of unnecessary work. Because it’s more object-oriented computer science backgrounds and the many people coming from languages such as Java, .NET, and C++ should find it welcoming. However I think in general the javascript community wants to move more towards functional programming, using object composition…

In this tutorial, we are going to cover how to use route guards with Angular routing to prevent access to certain routes if certain conditions have not been met.

Instead, we should use Angular’s route guards to prevent access to certain pages in an Ionic/Angular application.

Route guards make the process of protecting certain routes and redirecting the user quite simple, and in my opinion, more manageable than using navigation guards like on individual components.

Client-side code is modifiable by the user, so you should never use route guards to protect information that you don’t want the user to see (just as you shouldn’t solely use client-side code to validate/sanitise user entered data).

Once you have created the auth guard service (and it does not need to be called that) you will also need to make sure to add it to the for your application just like any other service: – – All that is left to do once you create the route…

In this tutorial, we are going to cover how to use route guards with Angular routing to prevent access to certain routes if certain conditions have not been met.

@joshuamorony:See how you will be able to prevent access to particular pages in @Ionicframework 4.x using @angular route guards:

In a previous tutorial, I covered how we would implement Angular routing in an Ionic 4.x application. When Ionic 4 is released, there will be more of a focus on using the baked in Angular routing, rather than Ionic’s own push/pop style routing (this style of navigation will still be available, though).

In this tutorial, we are going to cover how to use route guards with Angular routing to prevent access to certain routes if certain conditions have not been met. A common example of this is preventing access to certain pages if the user is not logged in, and that is what we will be focusing on.

In the past, you may have used the Ionic navigation guards like to determine whether or not a user could navigate to a page. However, I don’t believe these functions will be available in Ionic 4.x (I’m not 100% certain on this). Instead, we should use Angular’s route guards to prevent access to certain pages in an Ionic/Angular application.

The basic idea behind a route guard is that you attach a service which acts as the “route guard” to a particular route. That service has a method which will return either or depending on whether the user should be allowed to go to that route or not. If the method returns false, then the user will not be able to access the route.

Angular Services do NOT have to be Singletons – As you probably know, when we add a service to a @NgModule() declaration, it will be a Singelton.

For example: – export class AdminService { – data = providers: [AdminService, AdminDataService] – })I see a lot of people whose first instinct is to just put all their services in @NgModule() declarations without thinking about the consequences.

The sole purpose of the service is to share data between child’s components and to provide a couple of helper’s methods.

So, we just stick it in the component providers and make it a non-singleton service.

@Component({ – selector: ‘admin-tab’, – providers: [AdminService, AdminDataService] – })The benefit is that when Angular destroyed the component, she will also destroy the service and release the memory that is occupied by him.

As you probably know, when we add a service to a @NgModule() declaration, it will be a Singelton. Meaning, it will live as long as our application lives. For example: I see a lot of people whose…

You are not releasing memoryAlthough you probably do not need this memory anymore. Let’s stop for a second and think, do we really need this service to be a wide app singleton?

For example, in our application, we have an admin section where we need to display a big list of data which, of course, is stored in memory.

We don’t need this service to be a singleton. We don’t need a caching layer and no one out of this tab needs data from it.

The sole purpose of the service is to share data between child’s components and to provide a couple of helper’s methods.

So, we just stick it in the component providers and make it a non-singleton service.

selector: ‘admin-tab’,

providers: [AdminService, AdminDataService]
